2 Claims. (01. 12s--240) This invention relates to hygienic devices, and it has particular reference to syringe nozzles es pecially adapted to flushing and cleansing of anatomical organs, such as the vagina in female anatomy, and its principal object resides in the provision of a syringe nozzle having such form and appurtenances adapting the same particularly to the effective cleansing of the vagina of all accumulations of impurities, including mucus, and the like, which characteristically lodge in the muscular folds or crypts forming the walls of this organ, and providing a device which is peculiarly shaped to be readily projected, without discomfort, into the organ, and formed so that effective flushing of the posterior fornix may be accomplished, and the adjacent recesses can be thoroughly cleansed.

1 An object of the invention is that of providing a nozzle which maybe readily applied to a supply conduit, eithe1: attached to' the I plumbing, having a source of hot and cold Water, or to a suitable container, and also having an outlet or waste passage through which the liquids can be discharged to a waste container, the inlet and outlet passages being so arranged as to afford an adequate supply of flushing liquid through numerous spray orifices formed on the discharge end of the device, and providing a port rearwardly of the perforated discharge end of the nozzle for the outlet of the spent liquid into the outlet passage which spent liquid is sent to the waste container through a suitable conduit.

It is a prime object of the invention to provide a simple, economical and compact structure which is designed to afford a desirable and satisfactory means of maintaining feminine hygiene, enabling the user to guard against disease and discomfort caused by accumulation of im purities, and thus insure more abundant health.

Broadly, the invention contemplates the provision of a douche nozzle, particularly designed for the flushing of the vaginal cavity, and by its form; affording a more adaptable instrument than is commonly provided for such purposes, insuring a more efiective and forceful flushin stream into the natural folds and recesses of the organ.

While the foregoing objects are paramount, other and lesser objects will become manifest as the description proceeds, taken in connection with the appended drawings, wherein:

Figure 1 is a longitudinal cross-sectional View of the invention, on lines Il of Figure 2, illustrating the inlet and outlet passages through the main body, and showing the spoon-like form of the discharge head, arrows indicating the flow of the liquid through the device.

Figure 2 is a top plan view of the invention, showing the concave upper surface of the discharge head having a plurality of orifices therein, and illustrating, in dotted lines, a guard slidably arranged on the body.

Figure 3 is an inverted plan view of the invention, showing the convex undersurface of the discharge head, having a plurality of orifices therein, and illustrating the discharge port, the guard being shown in section on the body.

Figure 4 is a transverse sectional View, on lines 4-4 of Figure'z, of the concavo-c'onvex f'head,

Figure 5 is another transversese'ctional view, on lines 5-5 of Figure 2, showin'gith' longitudinal passages through the body-and the. outlet port in the bottom thereof..

Accordingly, the invention comprises acrimdrical body It) onwhich is'iormed adischarge head ll defining a spoon-shape. In a horizontal plane the head H is concave-convex, havin a concave upper surface l2 and a convex under surface It, both of which are provided with a plurality of orifices I 4. The orifices 14 also are formed around the perimeter of the head II, as is apparent in Figure 2. A chamber I5 is formed within the head II and is directly connected to an inlet passage It longitudinally of the body 10, and which passage is semi-circular in transverse section, as shown in Figure 5.

At the end of the body I!) opposite the head I I is connected a fluid-inlet tube H which communicates directly with the passage IE1 and has attached thereto a flexible conduit l8 through which Water is supplied from a source (not shown) flowing in the direction of the arrows shown in Figure 1. The floor 19 of the passage l6, shown more in detail in Figure 5, separates the passage I6 from the outlet passage 20 parallel thereto in the lower portion of the body ID,

as is apparent in Figures 1 and 5. The member I9 extends toward the head I! and merges into the bottom l3 thereof through a vertical portion 2|, shown in Figure 1.

Immediately behind the vertical portion or wall 2! is an elongated outlet port 22 providing a communication into the outlet passage 20 on the opposite end of which is connected an outlet tube 23 to which may be connected a flexible conduit 24 for the discharge of fluids to a waste container (not shown) in the direction indicated by the arrows.

It is desirable that the body in be formed of hard rubber or plastic, and preferably a clear plastic, or one which is transparent, so that it may be more readily cleansed and sterilized. "Obviously, such materials as rubber or plastic are more readily shaped to the conformations best adapted for the purpose for which the invention is intended.

A substantially cup-shaped guard 25 is arranged upon the body I and is slidable thereon for longitudinal adjustment, as shown in dotted lines in Figure 2, and in cross-section in Figure 3. It is desirable that the member 25' flare outwardly and away from the head I I, and be adjusted so that the element will serve as a stop,

enabling the use of the invention in the vagina at different depths. In no case, however, should the guard 25 be moved over the outlet port 22 inthe lower side of the body II].

It is apparent, therefore, that the invention is' considerably more effective than the conventional type of douche nozzle due to the peculiar form the art without departing from the spirit and intent of the invention or the scope of the appended claims.

What is claimed is:

1. In a douche syringe comprising a cylindrical body portion having a water-inlet passage ar ranged longitudinally through the upper section thereof, the combination of a spray head formed with said body portion having concavoconvex upper and lower surfaces and having a water passage therein communicating with the said inlet passage, a plurality of orifices spaced about said surfaces and about the perimeter of said head, a water outlet passage in the lower section of said body arranged parallel to said inlet passage, and a port communicating with said outlet passage rearwardly of said head in the underside of said body.

2. In a douche nozzle for a syringe having a cylindrical body portion formed with a waterinlet passage in its uppersection and longitudinally of said body portion, a relatively flat spray head formed with said body portion having a concave upper surface and having a bottom surface conformable to said upper surface, and communicating with said inlet passage, a water outlet passage formed in the lower section of said body parallel to said inlet passage, a portproviding communication from the exterior of said body rearwardly from said head and anteriorly of said body, and tubular means at the ends of said passages opposite said head for attaching inlet and outlet water conduits.
